Application filed. September 29, 1922. Serial No. 591,235.

To all whom it may concern:

Be it knownthat 1, WILLIAM J. S'rAUn- INGER, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Hedge Cutters, of which the following is a spec-1- fication.

This invention relates to hedge cutters, an object thereof being to provide an improved device which will be compact, light and relatively =simple in construction, easily and readily manipulated, relatively inexpensive to manufacture, and durable and serviceable in use.

Other objects of this invention will appear in the following description thereof, reference being had to the accompanying drawings forming a part of this specification wherein like reference characters indicate corresponding parts in the several views and wherein Figure 1 is an end elevation illustrating my invention. Fig. 2 is a plan view thereof partly broken away at one end. Fig. 3 is a fragmentary longitudinal sectiona'l view taken substantially on line 3-3 .of 2. 4 is a cross section taken in lines 4-4 of i g. 2. Fig. 5' is a fragmentary plan view illustrating the cutter blade with relation to the spacing barfor the supporting plates is a fra mentary plan view illustrating one end of t e device.

In the drawings T have herein illustrated a preferred embodiment of my invention, although of course it is understood that changes in the details of construction, form and design may be made without in any way departing from the spirit of the invention.

In carryingout my invention it will be seen that this improved hedge cutter comprises a pair of elongated supporting plates or bars 9 and 10 of suitable length andwidth, the supporting plates being placed in juxtaposition and alignment and having the forward edges thereof notched or cut away at suitable intervals to form preferably V-shaped teeth 11 and 12. Tt'will be seen that the teeth 11 of the top supporting plate 9 are in vertical alignment with the teeth 12 of the bottom supporting plate 10, and preferably the side edges of the bottom series of teeth 12, are beveled upwardly and cutting edges. The top and bottom supporting plates 0 bars 9 and tially the plates 9 of the device; and Fig. 6'

10 are held in spaced relation by means of a spacer bar 13, of substanthe same plates but is of less width than such lates. Through the medium of the bar or p ate 13 the supporting plates 9 and 10 are secured together, as by means of bolts 14 and nuts 15.

At one end ofthe supporting plates is mounted a Ufshaped bracket 16, the ends of which embrace the supporting plates-9 and 10 and are preferably bolted thereto as at 17. A short spacer or plate 18 is secured in position between the forward edges of and 10, this plate extending as far as the guide members and cutting teeth hereinafter described. A bearing sleeve 19 is secured to the bracket 16'and within this bearing rotates the arbor 20 of a suitable motor 21. This motor may be of any suitable character and is preferably an electrically driven motor of light construction. A supporting strap 22 embraces or surrounds the motor to which are secured a pair of supporting brackets 23 and 24, bolted to the supporting plates 9 and 10, A supporting brace 24 is also secured to the bracket 16' and bolted to the strap 22 as at 22 At the rear of the motor 21 is connected a suitable handle 25 and a switch 26 connected at 27 to the upper part of the handle is located in position forconvenient operation by the thumb of the user, power being transmitted to the motor by means of a cord connection 28.

At the forward end of. the'arbor 20 of the motor 21 is secured an eccentric 29. A crank arm 30 is pivotally connected'to this eccentric and is also pivoted to a reciprocating slide member 31, the supporting plate 9 being cut away at 32 to form a guideway for the slide 31. The bracket 16 is also which may be cut away at 33 to provide suitable space for the operation of the crank arm 30.

By means of the spacer plate 13 the top and bottom supporting plates 9 and 10 are spaced apart sufiiciently to form a guideway at the forward portion thereof for a reciproeating cutter blade or bar 34. bar is of less width than the width of the supporting plates and is located between the front edge 35 of the plate 12 and the forward ends of the teeth 11 and 12. The cutter bar 34 is notched out or cut away at intervals to form cutting teeth 36 of substantially the same size as the two series of al gn d tee h 11 a d 12 h QppQ ed ide length as-the supporting" This cutterthe cutter bar 34 as by means of suitable screws 38 and adjacent to the opposite end of the supporting plates a guide member 39 1s secured at 40 to the cutter bar 34 and operates in a slot 35 formed in the top supporting plate 11, the purpose of theguide 39 being to hold the cutter bar in proper relation to the suppoting plate during the operation thereof. Guide members 41 are carried by the: supporting plates and extend forwardly thereof. These guide members are any suitable manner.

preferably bifurcated at 42 and 43 so as to embrace the supporting plates and each aligned pair of teeth Hand 12 is provided with a guide member41 which is secured in The members 41 are preferably blunt at their forward ends and form not only means for guiding the .mate-. rial to be cut into the path of operation of the cutting teeth but also form guards for preventing inadvertent injury to the user. It will be noted that the motor 21 with the handle 25 connected thereto is mounted at one end of the supporting means, and adjacent to the opposite end thereof ismounted a handle 44 which is also bolted to the supporting means at 45.

From the foregoing construction it will be seen that an improved hedge cutter of relatively simple and inexpensive construction is provided. 7 The device is relatively light and easy to handle, and the position of the handles and motor with relation to the supporting means is such as to provide a well balanced structure which can be manipulated with eat facility. It will also be noted that t e bottom supporting plate 10 is provided with cutting teeth which cooperate with the cutting teeth of the reciprocatin cutter bar, and that the teeth 36 of the latter operate within the area of the supporting plates. The entire device is constructed with a minimum number of parts and may be very quickly assembled and dismounted. The cutter bar 34 can be readily and quickly removed merely by removing the screws 38 and 40 and then sliding the cutter bar endwise from between the plates-9 and 10.

It will be understood that bydescribing in detail herein any particularform, structure, or arrangement it is not intended to limit the invention beyond the terms of the several claims or the'requirements of the prior art.
